Dev Container Connection Unstable (WSL Ubuntu 22.04 Using Podman)

[bramankp]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.84.0-insider
• OS Version: Windows 10, WSL Ubuntu 22.04

Steps to Reproduce:

1. WSL Ubuntu 22.04
2. Install Podman
3. Configure VSCode ["dev.containers.dockerPath": "podman"]
4. Open Dev Container on project.
5. Witness VSCode ManagementConnection continually reconnecting.

If you install Docker WSL Ubuntu 22.04 and reconfigure to use "docker" it is stable.

If you reproduce this on WSL Ubuntu 20.04 (using Podman) it is stable.

There is a tangible benefit to using Podman for the container service and this works on 20.04. Why doesn't it work on 22.04?

What are the Podman versions you are using on Ubuntu 20.04 and 22.04? This sounds like it might be a Podman issue.

[bramankp]

3.4.2 on Ubuntu 20.04 3.4.4 on Ubuntu 22.04

I mean it could be a podman issue but the key here is figuring out if it is (or if it's reproducible) so we can communicate with that team and figure out the solution (if there is something they need to do to fix it).

Please append the Dev Containers log from when this happens. (F1 > Dev Containers: Show Container Log)

I have the same issue using Ubuntu and podman 4.3.1 or 4.9.2. "Fun" fact, it does work properly on a Debian with podman 4.3.1. The symptom is as in the log provided (here in trace mode):

After more investigations, the issue is coming from the podman side. common is breaking. An update is necessary to 2.1.2. For example:

wget https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_22.04/amd64/conmon_2.1.2~0_amd64.deb -O /tmp/conmon_2.1.2.deb
sudo apt install /tmp/conmon_2.1.2.deb

Hey @chrmarti, this issue might need further attention.

@bramankp, you can help us out by closing this issue if the problem no longer exists, or adding more information.

[bramankp]

Adding a note that Ubuntu 24.04 LTS seems to work fine. So I suggest everyone avoid that middle step-child of 22.04 if they run into this problem and can use the more recent version of LTS. :)
